As we follow the national motorway from Katerini to Elassona, after the village of Milia, we pass along an impressive densely-wooded gorge that divides Mount Olympus from the smaller Mount Titaros. These are the famous “Petra narrows”, one of the three big passes of Olympus from ancient times to the present. The gorge waters are used to irrigate fruit trees and “pezoules” (terraced cultivations) where the renowned Agios Dimitrios beans are cultivated; the area used to have watermills and “Mantania” (Fulling Mills). 33 km from Katerini lies the village of Agios Dimitrios which was formed from smaller villages in the 15th century. Many of the villagers were executed during the German Occupation due to their participation in the national resistance and the village was burned down three times by the Occupation forces. The Village of Agios Dimitrios still preserves old stone-built houses with wooden balconies, while the shops and taverns offer local products.
